I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Bruce Lee (Chinese: 李小龍; born Lee Jun-fan, 李振藩; November 27, 1940 – July 20, 1973) was a Hong Kong and American martial artist and actor. He was the founder of Jeet Kune Do, a hybrid martial arts philosophy drawing from different combat disciplines that is often credited with paving the way for modern mixed martial arts (MMA). Lee is considered by critics, media, and other martial artists to be the most influential martial artist of all time and a pop culture icon of the 20th century, who bridged the gap between East and West. He is credited with promoting Hong Kong action cinema and helping to change the way Asians were presented in American films.
Truth has no path. Truth is living and, therefore, changing. Awareness is without choice, without demand, without anxiety; in that state of mind, there is perception. To know oneself is to study oneself in action with another person. Awareness has no frontier; it is giving of your whole being, without exclusion.
